SPECIFICATION forming part of Letters Patent No. 620,956, dated March 14, 1899.,

Application filed April 13, 1898. Serial 1%. 677,403. (No model.)

T0 at whom it may concern:

Be it known that I,WiLHELM E. NAGEBORN, a citizen of the United States, residing at Detroit, in the county of 'Wayne and State of Michigan, have invented certain new and useful Improvements in Button-Drilling Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to multiple drillingmachines especially designed for drilling buttons; and it is the object of my invention to obtain a machine in which any desired number of holes may be drilled in the buttons and in which a button is completed with each operation of the drills.

The invention consists in the peculiar construction of the carrier adapted to present the buttons successively to the different drills; further, in the construction of the in- 1 dividual button-holding chucks of which said carrier is composed; further, in the means employed for opening said chucks to place a button therein and for automatically disen gaging the completed buttons from their chucks; further, in'the means for'operating and adjusting the positions of the drills, and, further, in the peculiar construction, arrangement, and combination of parts, as more fully hereinafter described and claimed.

In the drawings, Figure 1 is a perspective view of my button-drilling machine. Fig. 2 is a sectional plan view thereof. Fig. 3 is a vertical longitudinal section on line 5000, Fig. 2. Fig. at is a cross-section on line y 11 Fig. 2. Fig. 5 is a bottom plan view of the bed. Fig. 6 is a perspective View of one of the chucks. Fig. 7 is a cross-section thereof. Fig. 8 is a perspective view of some of the parts detached. Fig. 9 is a cross-section through a bearing for one of the drill-spindles. Fig. 10 is a plan thereof.

A is a table or bed, in the upper face of which is formed a rectangular annular groove or channel B around a central panel C.

D are a series of chuck-blocks which are of rectangular form and of a diameter equal to the width of the channel B. These blocks are slidingly secured in the said channel, the

lengths of the sides of which are exact multi ples of the diameter of the blocks, the depth of said channel being also approximately the same as the thickness of said blocks.

Each chuck-block is provided with plates or jaws a 01., which are slidingly secured upon the upper face of the block, preferablyin the undercut guides or slideways b thereon, and each jaw is provided with a V-sha-ped notch c, which notches together form a recess at the center of the chuck-block above a smaller aperture d, passing through said block. The outer edges of the plates a and a are oppositely inclined or wedge-shaped, .and e is a plate having the bifurcated wedge-shaped arms f, adapted to embrace the plates at and a. and bear against the inclined. edges thereof. The plate 6 is secured in undercutor dovetailed guides or slideways 9, arranged at right angles to the slideways b.

h are pins extending downward from the under side of the plate e into slot 2' in the blocks, arranged parallel to the guides g. These slots communicate with the recesses j inthe blocks, in which are placed the springs in, hearing at one end against the screwthreaded plugs Z and at their opposite ends against the sliding blocks m, which bear against the pins h, the arrangement being such that the springs 70 will hold the plate 6 normally into position, where it will wedge the two sliding jaw-plates a and a together. The meeting edges at the outer ends of the plates at and a are cut away to form a V- shaped notch 11., and the opposite edge of the block D has formed therein the V-shaped notch 0. The corners of the blocks are preferably rounded slightly, as shown.

The chuck-blocks D. are placed in the groove B so as to have the notch u toward the front and the notch 0 toward the rear of the bed, and the number of the blocks is two less than that required to completely fill the channel 13-1. 6. so as to leave the diagonally opposite corners vacant.

E, E, E and E are pusher-arms for the blocks D, arranged, respectively, at the four corners of the channel B and normally withdrawn into recesses F in the sides of said channel. These arms are adapted to be reciprocated to push along the row of blocks in each side of the channel B, the diagonally opposite arms operating simultaneously and alternately with the other diagonally opposite pair. These arms pass downward through slots F in the bottom of the channel and are connected with suitable mechanism on the under side of the machine for reciprocating them in the manner above described. This mechanism, as shown in the drawings, comprises the bars G, G, G and G slidably secured in bearings on the under side of the bed and to which the pusher-arms are secured.

H is a rotary head journaled centrally on the under side of the bed and provided with the arms H and H 1 and I are arms or projections secured to the sliding bars G and G respectively, and with which the arms H and I l are respectively adapted to engage in the rotation of the head H to slide said bars in one direction in their bearings.

J and J are levers having their opposite ends connected, respectively, to the bars G G and G G said levers being adapted in the movement of the bars G and G to impart an opposite movement to the bars G and G. These levers are pivoted on the under side of the bed, the lever J being preferably fulcrumed on the spindle of the head H and the ends of both levers being slotted to slidingly engage with pins on the bars.

1 is a lever, one end of which is connected to the bar G and the opposite end extending into the path of the arm H on the head H.

I is an arm on the lever J, which also extends into the path of the arm H said arm I and lever I being adapted to impart a reverse movement to the bars from that imparted thereto by the engagement of the arms II and H with the arms I and 1, respectively.

K is a drive-shaft extending longitudinally and centrally below the bed and journaled in bearings at the opposite ends of said bed.

K and K are 1niter-gears connecting the shaft K with the head H.

K is a cam at one end of the shaft K.

L is a rock-shaft extending longitudinally near the rear side of the bed and journaled in bearings thereon.

L is a rock-arm on said shaft, extending down into proximity to cam K M is a bar extending along the rear edge of.

the bed, to which is secured a series of fingers M, adapted to slidingly engage with slots in the bed extending into the channel B. These fingers are arranged to be opposite the centers of the chuck-blocks in the rear side of the channel 13 and are V-shaped at their inner ends to engage with the V-shaped notches o in said chuck-blocks.

M? are springs tending to force said fingers inward.

L and L are rock-arms on the rock-shaft L, adapted to bear against the ends to force said bar outward and disengage the fingers from the chuck-blocks.

N is a supporting-frame for the drill-spindles, comprising the end posts N and the horizontal bar or plate extending longitudinally above the rear row of clutch blocks in the channel B.

O are the drill-spindles, vertically slidingly secured in bearings O, secured to the frame N centrally above each of the chuck-blocks. The bearings O are provided with a limited lateral adjustment by means of screws 0 engaging with slots in flanges O resting on the frame N.

O are pinions on the spindles O, which are connected to each other by intermediate pinions O one of which is mounted upon the drive-spindle 0. 'These pinions are journaled on stub-axles, which are also capable of lateral adjustment on the frame N.

P is a vertically-sliding frame having the laterally-extending arms P adj ustably secured thereto and forked or slotted at their outer ends to engage with grooved collars O on the spindles O.

P are springs sleeved upon the vertical members of the frame P and tending to hold said frame in its raised position.

Q is a rock-shaft journaled in bearings below the bed and having the rock-arm Q, adapted to engage with the cross-bar P on the frame P, and the actuating rock-arm Q engaging with a cam K on the shaft K.

At the forward edge of the bed is arranged a sliding plate R, having the projecting points adapted to engage with the V shaped notches a of two of the chucks. This plate is also provided with the projections s, adapted to strike against the bifurcated ends fof the sliding plates 6 of said chucks.

S is a rock-shaft journaled in hearings on the forward side of the bed and having the rock-arms S, adapted to bear against the plate R.

S is a rock-arm on one end of the shaft S,

extending into engagement with a cam K on.

the shaft K. I

T is a pin vertically slidin gly secured in an aperture int-he bed below the channel 13 and at a point to be in registration with the central aperture d of the chuck-blocks when in the position indicated by the letter X, Fig. 2. This pin is secured to the plate or head'T 'below the bed, which is adapted to be raised by the rocking of the pivotal arm or lever T so as to project the pin upward through the aperture d of the chuck-block. The arm of lever T is operated by the arm H on the head H, which in the rotation of said head comes into contact with the end T of said lever, depressing said end and raising the opposite end, which contacts with the under side of the plate T and raises it. To hold the plate in its raised position temporarily after the arm 11 has disengaged from the lever T a latcharm S is provided, adapted to catch under said plate and having an engagement with the rock-arm S, by means of which it is subsequently tripped in rocking said arm.

U is an arm secured to a vertical rock-shaft U at one edge of the bed, adapted to sweep over the top of the bed and having a notched end U which passes over the center of the chuck in the position indicated by the letter X.

U is a slotted actuating-arm for the arm U, arranged below the bed and engaging with a pin on the reciprocating bar G The parts being constructed and arranged as shown and described, the operation of the machine is as follows: Motion communicated to the shaft K will cause the cam K thereon to actuate the arm S which will rock the shaft S and arm S thereon, causing the latter to press against the plate R and slide said plate in its guides. This will cause the projections s to press against and move backward the wedge-arms f of the plates 6 on the two adjacent chuck-blocks at the position marked X and Y, Fig. 2. At the same time the pointsr on the plate will enter the notches u of said chucks and spread the jaws a a thereof apart. The operator now places a button-blank in the recess formed by the notches in the jaws of that chuck at the position marked Y. The further movement of the shaft K will release the pressure of the arm H into engagement with the arm or lug I on the sliding bar G Fig. 5, moving said arm toward the right and through the connecting-lever J imparting a reverse movement to the bar G. The movement of the bars will cause their corresponding pushers E and .E to push the rear and front rows of chuck-blocks respectively toward the right and the left, Fig. 2, filling the previously-vacant diagonally-opposite corners Z and Z and leavingvacant the cornersZand Z Another chuck-block is thus brought into the position Y, which will have its jaws spread to receive a button-blank in the manner before described. The aim H after disengaging fromthe arm I will next come into engagement with the arm I on the lever J, which will cause a reverse movement of said lever and the bars G G carrying the pushers E and E back to their original positions in the recesses F. The arm H will then come in contact with the arm or projection I on the sliding bar G, moving that bar and through the connecting-lever J simultaneously reversely moving the bar G so as to cause their respective pushers E and E to move the said rows of chuck-blocks, the row on the left hand side, Fig. 2, being moved toward the rear and that on the right-hand side toward the front of the bed. This set of sliding bars will thus feed the entire series or chain of chucks forward by the space of one chuck, and when the chucks having the blocks engaged therewith arrive at the rear side of the channel they will hold the blanks in operative relation to the drills. then imparted to these drills through a suitable belt connection to a pulley O on the spindle O and from the latter through'the pinions O and O to each of the drill-spindles O, which are provided with suitable chucks at their lower ends for holding the drills. In the drawings I have shown five of these drill-spindles, as that is the largest number of holes generally formed in a button; but any number of spindles maybe employed, and when the machine is used for buttons requiring a lesser number of holes the extra spindles may be thrown out of operation by re moving the intermediate pinions 0 or they may be left in operation and the drills only removed. During the interval in which the chucks O are at rest the cam K on the shaft K willrock the arm Q on the rock-shaft Q and cause-the rock-arms Q on said shaft to depress the bar P of the vertically-sliding frame P, carrying said frame downward and causing the arms P, engaging with the grooved collars O to carry down the spindles O, pressing the drills through the buttonblanks in the chucks below. The position of these drill-spindles in relation to the centers of the button-chucks beneath is such that each Will bore a hole at a dilferent point in the button, and in order that the position of these holes may be precisely the same in each button I provide means for holding all the chucks beneath the drill-spindles during the time of drilling. This is accomplished by the fingers M, having the V-Shaped ends, which are moved inward by the springs M bearing against the bar M and engaging said fingers with the V-shaped notches 0 in the chuckblocks. After the drilling is performed, but before the chuck-chain is again set in motion, the cam K will rock the arm L, rock-shaft- L, and rock-arms L causing the latter to push back the bar M and withdraw the fingers M into their slots in the bed. Just before completing the circuit each of the chuck-blocks will be brought into the position X, Fig. when in therotation of the head H the arm H thereon will rock the lever T causing it to lift the plate '1" and force the pin I upward through the aperture d in the chuck. This will lift the finished button above the jaws a and a of the chuck, which jaws have been previously spread by the operation of the projections s and points r on the plate R, andv hold the button in this position until the arm or sweep U is swung around and carries it over the edge of the bed, droppingitinto the hopper V.

Although I have shown and described a machine as employed for drilling the buttons, it is obvious that the same mechanism might be employed in connection with other forms of Rotary motion is tools-such, for instance, as the facing-tools. I have also described the chuck-blocks as of rectangular shape and traveling in a rectangular groove in the bed; but this may be varied by forming the groove of any polygonal shape, provided that the chuck-blocks are of a similar polygonal form.
